I’ve wanted a Whitcomb for years and when asking guys in the Modutrak group if they had ever seen one Mark (Elgin Locomotive Works) says Yeah, I’ve had that modeled in Solidworks for years. He put the shell in my hands at RPM Chicagoland last weekend.

Here we go.
The hoods are to scale and narrow but after milling out some wall thickness a 6x15 coreless motor fit nicely.

I’m using the trucks from a Kato 11-106 powered chassis. Since the motor is a single shaft it will be one truck powered.
There’s no width in the hood to let the geared truck pivot but that doesn’t matter since this is so short.
I milled a pocket in the sill that lets the clever stock Kato clip hold the truck in place. The clip also holds the worm and shaft bushings.
The horizontal lines above and below the pocket are a slight step up on the chassis and also the outline width of the hood. The nice narrow hood covers the pocket but only by about.010” on either side.

The other truck pivots on the stock post which was cut from the donor chassis and epoxied into a slot milled in the printed chassis.

The motor rests in a shallow slot milled in the chassis low enough to match the motor and worm shafts. It’s soft mounting on canopy glue.
The shafts are different diameter so I turned a brass flywheel/ coupling with the appropriate size hole drilled in either end. Red Loctite holds everything together.

There’s a Lokpilot decoder and TCS keep alive in the cab.
First test runs were promising so detail and paint will commence.
Here’s a short video of the test run.
